Work Life: C# Web Service Errors

No spaces in name of XElement

Error Message:

System.Xml.XmlException: The ' ' character, hexadecimal value 0x20, cannot be included in a name.

This is because I had used:

XElement root = new XElement("List Of Members", e1, e2, e3);

... which should have been:

XElement root = new XElement("ListOfMembers", e1, e2, e3);

Parameterless Constructor

Error Message:

cannot be serialized because it does not have a parameterless constructor

This was because I was trying to return a variable of type XDocument which does not have a parameterless constructor. I then tried return specific classes, but still received this error because my classes did not have parameterless constructor.

Basically what the compiler is looking for is the follow:

public Class1
{
  Class1()
  { }
}

The constructor can also be private or internal if you do not want to have a public parameterless constructor.
